Specification of Letters Patent.

Patented Apr. a, 1917.

Application filed September 11, 1913. Serial No. 789,232.

To all whom it may concern:

Be it known that l, CLINTON A. HAGA- noun, a citizen of the United States, residing at Vestern Springs, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in J 0urnal-' Bearings, of which the following is a full, clear, and exact specification.

My invention relates to journal bearings, and in its general adaptation is particularly designed for use in connection with corn huskers wherein rotatable coacting rollers running in opposite directions operate to strip the husks from the ears of corn as they pass along between the opposing rolls. The object of my invention is to provide an improved construction whereby the rolls are yieldingly held close together under normal conditions, and permitted to separate when other conditions prevail in the operation of the machine. I attain these objects by means of mechanism one embodiment of which is illustrated in the accompanying drawings, in which Figure 1 represents a top planview of a part of a corn husking machine having my invention embodied in its construction; and

Fig. 2 is a cross section ofFig. 1 along line A-B.

The same reference numerals designate the same parts throughout the several views.

1 represents a pair of spaced bars forming part of the frame construction of a corn husker, 2 a bracket member having a leg portion 3 provided with a boss member 4c that is received between the spaced bars 1 and provided with an axial opening that receives a securing bolt 5, and 6 represents a downward extension of the leg portion terminating in a collar member 7 and a pintle member 8. 9 represents a supplemental leg spaced apart from the leg 3 along a longitudinal central. line of the bars 1 and having a boss portion 10 that is received between the bars 1. and a bolt 11 clamps the associated parts together. 12 represents a pair of spaced lip members that contact with the upper edge of one of the bars in a manner to assist in keeping the bracket member 2 in proper position relative to the spaced frame bars. The bracket member is provided above the bars with an opening 13 that receives the bearing box 14, that is provided with a collar member 15 intermediate its ends that fits closely within the opening in.

the bracket, and a radially disposed ear 10 upon one side that engages with the surface of the bracket in a manner to limit a longitudinal movement of the bearing boX in one direction, and upon the opposite side with a peripheral rib 17 that is notched at its central portion to receive a projecting block member 18 integral with the bracket and operative to prevent a rotative movement of the bearing boX within the bracket. The bracket member '12 is also provided with a laterally projecting hook member 19 at its upper end. 20 represents an opposed bracket member pivotallv mounted between the bars 1 and adapted to receive the bearing box at in the same way with bracket 2, and 21 represents a downwardly extending arm that terminates in a sleeve member 22, in which is threaded an adjusting screw 23 provided with a locking nut 2-1 at one end of the sleeve and a loose cap member 25 at its opposite end. 26 represents a compression spring interposed between the cap and the oppositely disposed extension 6 of the bracket 2 and operative to normally swing the bracket member 20 about its axis and in contact with the bracket 53, flattened surfaces 27 upon the opposing members shown in dotted lines on Fig. 2, limiting an inward swing of bracket 20. 28 is a complemental hook member at the upper side of the bracket 20 adapted to engage with the hook 19 in a manner to limit an outward swing of said bracket. The bearing box 14 receives bushings 29 in a common way, in which are ournaled the sh alts 30 of the opposing husking rolls 31, that are rotated in opposite directions by means of a bevel gear 32 secured to a cross shaft 33 and ei'igaging with a bevel pinion 53 i secured to another shaft 30 integral with a husking roll, said shaft having secured thereto a spur pinion 35 that meshes with a like pinion secured to the opposing roll. in a common way. a

In operation the rapidly rotating husking rollers receive the husks between them, and when bunches of husks or some foreign material with bulk enough cause the bracket member 20 to swing away from the opposing bracket, the hook members 28 and 19 limit such movement and spring 26 restores the bracket to its normal operative position.

While my improved form of journal bearing is designed primarily for use in connection with corn husking machinery, it may be used for any other purpose for which it is adapted, and I wish it to be understood that I do not limit myself to the specific form of mechanism herein claimed, as many variations may be made without departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is: p

1. In a journal bearing, a supporting frame, and journal carrying brackets mounted side by side upon said frame, one of said brackets being permitted angular movement and directly engaging with the yieldingly resist such movement in one direction, and interengaging parts carried by said brackets and operative to limit an angular movement in the same direction.

4. In combination, a frame, a plurality of bearing brackets carried thereon, one of said brackets being fixed with respect to the frame and the other being pivotally mounted thereon, cooperating rolls journaled in said brackets, means intermediate said brackets for yieldingly resisting movement of one of said rolls, and means for limiting the same movement.

5. In combination, a frame,'a plurality of bearing brackets carried thereon, one of said brackets being fixed with respect to the frame and the other being pivotally mounted thereon, cooperating rolls journaled in said brackets, means for permitting a yielding movement of one of said rolls and brackets, and interengageable means carried by said brackets for limiting such movement.

6. In combination, a frame, a bearing bracket pivoted thereon and having a depending shank, a cooperating bearing bracket fixed to said frame and likewise having a depending shank, a resilient connection between said shanks, and interengageable hook members carried on said bearing brackets limiting the separation of the same.

7 In combination, a frame, a bearing bracket carried thereby and having a lug thereon, and a bearing member seated in said bracket having a peripheral lug thercon engaging with the surface of said bracket member and locking said bearing member and bracket against longitudinal separation, said bearing member also being provided with a peripheral shoulder having a notch therein receiving the lug on said bearing bracket and locking said bearing member and bracket against relative rotation.

8. In a journal bearing, a supporting frame, opposing journal carrying brackets independently mounted upon said frame, one being rigidlv secured to said frame and one being permitted angular movement axially thereon, a compression spring operative between the movable bracket at one side of the axis thereof and the fixed bracket, and a member carried by the movable bracket at the opposite side of its axis and engaging with the fixed bracket in a manner to limit movement of said movable bracket against the force of said spring.

9. In a journal bearing, a supporting frame including a pair of bars spaced apart, a journal carrying bracket secured between said bars, and provided with an extension, and an opposing journal carrying bracket pivotally mounted between said bars and provided with a downwardly projecting arm upon one side of its axis, a compression spring operative between said arm and the extension upon the fixed bracket in a manner to normally hold said brackets in contact, and a member carried by the movable bracket upon the opposite side of its axis and adapted to engage with the fixed bracket in a manner to limit an angular movement thereof against the force of said spring.

In testimony whereof I aiiix my signature, in the presence of two witnesses.

CLINTON A. HAGADONE.
